CodeMeaning
577-0577-0 on a KitchenAid dishwasher is a control board internal fault code that appears in the service diagnostic mode rather than during normal operation. It indicates that the control board has logged a specific internal fault in its memory. This code is typically read during a service call using the built-in diagnostic sequence rather than appearing spontaneously on the normal display.

8-4The 8-4 error code on a KitchenAid dishwasher means the control board detected a heater circuit fault - the heating element did not raise water temperature to the required level within the expected cycle time. This numeric code appears on KitchenAid models with a digital display and is equivalent to the Clean light 7-blink code on indicator-only models.
mediumintermediate
9-1The 9-1 error code on a KitchenAid dishwasher means the diverter disc did not move to its expected position during a cycle. The diverter system routes wash water between the lower, upper, and (on KDTM models) third rack spray zones. When the diverter disc fails to advance to the next position, the control board registers 9-1. This is the same fault as Clean light 9 blinks on models without a numeric display.
mediumintermediate
CLEAN-4-BLINKFour blinks of the Clean light on a KitchenAid dishwasher means the water temperature thermistor is open - the control board is not receiving a valid temperature reading from the thermistor that monitors wash water temperature. The dishwasher cannot regulate heating properly without this sensor.
mediumintermediate
CLEAN-7-BLINKSeven blinks of the Clean light on a KitchenAid dishwasher means the control board detected a fault in the heater circuit. The dishwasher's heating element did not raise the water temperature to the target level within the expected time. This code corresponds to fault 7-1 in models that display numeric codes.
mediumintermediate
CLEAN-8-BLINKEight blinks of the Clean light on a KitchenAid dishwasher means the control board has detected low wash performance - the dishwasher completed a cycle but the washing conditions (water pressure, temperature, or spray arm function) were below minimum thresholds. This is not typically a component failure - it is a performance fault that points to maintenance issues.

CLEAN-9-BLINKNine blinks of the Clean light on a KitchenAid dishwasher means the diverter valve or diverter disc motor has a fault. The diverter system controls which spray arm zone receives water during the wash cycle - routing water between the lower spray arm, upper spray arm, and (on KDTM models) the third rack spray bar. A failed diverter means water may only spray from one zone.
mediumintermediate
E1 F9E1 F9 on a KitchenAid dishwasher means the control board detected that the drain cycle took longer than the allowed time - typically 2 minutes without the float switch being satisfied. The dishwasher shuts down to prevent flooding. The cause is almost always a physical restriction in the drain path rather than an electrical component failure.

E4 F8E4 F8 on a KitchenAid dishwasher is the same fault as F8 E4 - a water fill failure or anti-flood float trigger. The code is displayed in two different orders across KitchenAid models depending on software version. Both E4 F8 and F8 E4 mean the dishwasher either did not fill with water in time or the base pan anti-flood float was raised by accumulated water.

F8 E4F8 E4 on a KitchenAid dishwasher means the control board did not detect that the dishwasher filled with water within the expected time, or the anti-flood float switch under the unit has been triggered by water in the base pan. The dishwasher shuts down to prevent damage. This is the highest-volume fault code for KitchenAid dishwashers.
mediumbeginner
F9 E1F9 E1 on a KitchenAid dishwasher is the same long drain fault as E1 F9 - the control board detected that the drain cycle exceeded the allowed time. The two display orders (F9 E1 and E1 F9) refer to the same fault and appear on different KitchenAid models depending on firmware version. The drain did not complete within 2 minutes.

HUBKitchenAid dishwashers display fault codes in three formats depending on the model: alphanumeric codes (F8 E4, E1 F9), numeric codes (8-4, 9-1, 577-0), and blink codes on models without a numeric display (the Clean light blinks in patterns). Understanding which format your model uses is the first step to diagnosis.
mediumintermediate
POPO on a KitchenAid dishwasher display is not an error code. It means the Delay Start feature is active and the dishwasher is waiting to begin its cycle at the programmed delay time. The dishwasher is counting down the delay period and will start automatically when the countdown reaches zero.
